Chief of police Mike Wyeth is retiring later this year
Guernsey's outgoing chief of police has branded the island's judicial system as "unfair, unreasonable and unjust".
Chief Officer Mike Wyeth, who is retiring later this year, said the current system, which goes against the police, prosecution and victims of crime, needed to be rebalanced.
The condemnation relating to the way evidence has to be given before trial came in Mr Wyeth's last annual report.
In Guernsey, the prosecution is required to disclose evidence before a trial, while the defence is not.
Mr Wyeth said this could lead to prosecution cases being ambushed at the last minute.
The links between alcohol and drug abuse and the increase in robberies and burglaries are of the greatest concern to the police chief.
Alcohol abuse is also blamed for a 52% increase in the number of assaults last year.
While there is a 16% rise in reported crime in 2002, compared with the previous year, Mr Wyeth said the Guernsey crime rate was still one of the lowest in the British Isles.
